FIELD

This disclosure relates generally to data processing and, more particularly, decomposing a task of a workflow.

BACKGROUND

In increasingly complex business operations, a business process might be formalized using a workflow management system. The workflow management system typically includes a workflow engine that generates work items according to activities defined as workflows supporting one or more business processes. As an example, an organization might have a set process for approval for particular activity and the workflow management system handles routing a corresponding work item among those individuals that need to sign off on the approval. For example, an employee desiring a vacation might initiate a “vacation approval” business object. A vacation application would then send an event to the workflow management system, along with a reference to the business object (vacation request) and the workflow management system would pick and start a workflow that corresponds to the triggering event. The vacation approval request would be routed among those others that would need to track, approve or just be notified of such a request, with a result of the work (e.g., approval, denial, etc.) routed back to the initiating employee.

The work items needing a particular person's input or notice might be presented to that person or role as an item on a worklist. In some cases, work items can be acted on directly from a presentation of a worklist, while others are acted on by the workflow participant taking an action outside the worklist. In addition, participants may have other tasks and collaborative events.

Some interactions might use the workflow management system in part and use unrelated applications in part. For example, a work item might be generated for handling by a user that prompts the user to make a decision that requires information not present in the work item. For example, the work item might specify that employee A wants to take N days of vacation from date D1 to date D2 and request an approval/rejection response from the participant to whom the work item is assigned. That participant might then have to obtain further information externally, such as by conferring with A's group manager and relevant project managers, as well as checking with a human resources department or human resources application to determine if A has sufficient vacation time available.

DETAILED DESCRIPTION

During the course of a running process (e.g., a process instance), tasks may need to be performed by a user (e.g., an approve an order). The most common way of realizing this is to assign such tasks as work items for a group of people (so-called “potential owners” of the task), and wait until someone (e.g., the so-called “task owner”) in the group selects one or more of the tasks. When a user opens an assigned task using a user interface, the user interface enables the user to work on the task. The user interface will present information relevant to the processing of the task. In some cases, the user interface includes fields (or icons, etc.) to allow data to be entered into, for example, a form that will be relevant to subsequent processing (e.g., execution of the running process to approve or reject an order).

In some instances, it is often the case that a single task, although picked by a single user, requires information which is provided by other users (e.g., the actual task owner does not have the right information at hand to complete the task and must call someone else to obtain the right information). Traditional workflow systems do not support such scenarios. This is why ad-hoc actions, such as e-mails, phone calls, and the like, are used to get the information and correctly process the task. Recent improvements in workflow systems may allow for delegating a task (e.g., making another person the actual owner), but this seldom is the right mechanism to cope with the ad hoc situation. For example, the original owner of a task may not want to hand a task over to another user, the user may only need some information to complete the task of the worklist. Moreover, the original owner might not even be allowed to assign responsibility of the task over to another user because the task might contain sensitive information.

In some implementations, the subject matter may be used to decompose a task into a plurality of tasks. The original task owner may invite one or more other users to jointly solve a task by decomposing the task into one or more tasks (e.g., subtasks). When inviting one or more users to assist with a task, the original owner may restrict the data the invitee(s) may see or edit (e.g., data might be hidden, read-only, or not modifiable). This can be done for each invitee separately. The invitees may be presented via a user interface with the same form that the original task owner was presented with; however, the invitees may be presented with portions of the information (e.g., a form presented at the user interface) hidden, restricted, not editable, and the like. Furthermore, the original task owner may decide whether to have the task returned (e.g., in a task inbox) when the invitee provides information (e.g., in the case or the order approval above, the invitee may add information to the form presented at the user interface, and then the updated the form to the original task owner's inbox). In some cases, less critical tasks may not be controlled (i.e., returned to the original task owner's) inbox.

In some implementations, the advantage of task decomposition is that the original task owner configures the final outcome of the task before the task is completed. Moreover, the original task owner has control over which invitee is allowed to see or edit portions of information related to a task. In addition, a decomposed task allows the original task owner to better control the task outcome and impose visibility constraints. In contrast to the decomposed task approach described herein, a collaborative task approach does not have controls to, for example, restrict the visibility of data presented at a user interface since each participant has the same rights and can even complete the task.

FIG. 1 depicts a system 100 including a user interface 105 and a server 160, both of which are coupled by a communication mechanism 150, such as the Internet, an intranet, and the like.

User interface 105 may be implemented as processor including any type of interface mechanism for a user, such as a web browser, a client, a smart client, and any other presentation mechanism.

Server 160 may be implemented as any type of processor (e.g., a computer, a blade, and the like). Server 160 may also include a workflow application to control and process a workflow. Server 160 may also include a task decomposer 162 for decomposing a task. The task decomposer 162 may perform one or more of the task decomposition functions described herein including one or more aspects of process 200; generate form 400 (FIG. 4) for presentation (e.g., as an hyper text markup language page) at a user interface; control aspects of a workflow; receive from a user interface a selection for decomposing a task from a workflow including a plurality of tasks; receive, at the server, an indication from the user interface, the selection reflecting whether one or more portions of information (e.g., fields of the form 400) associated with the decomposed task are restricted; and provide to another user interface the decomposed task including the one or more restricted portions. In some implementations, the task decomposer 162 may decompose tasks for a workflow management system for managing tasks configured as a worklist.

FIG. 2 depicts a process 200 for decomposing a task using, for example, system 100. The description of process 200 will also refer to FIGS. 1A-B and 3.

At 240, a task is selected from a workflow for decomposition. For example, a user at user interface 105 may select a task for decomposition. The selected task may be a task selected from a workflow (and/or worklist) of tasks, such as tasks associated with a workflow management system. FIG. 3 depicts an example of a workflow 300 including three users (e.g., secretary 302, professor 304, and accountant 306). The workflow 300 includes receiving an application 310 (e.g., an application form is received at user interface 105 as an email from server 160) and filling out the application form 312 (e.g., by secretary 302 at user interface 105). During the completion of the completion of the form, the secretary 302 cannot complete the application form because the secretary 302 lacks sufficient information (e.g., the secretary is unsure of the salary amount to include on the application form). When this is the case, the secretary 302 may select the task 312 for decomposition.

At 244, one or more portions of the form may be restricted. For example, once task 312 of the workflow is selected for decomposition, the secretary 302 may restrict aspect to portions of the application form presented as a user interface. Returning to the above example, secretary 302 may restrict the entire application form as read-only except for the salary portion, for which the secretary 302 seeks input from another user. Moreover, the restriction may be made with regard to the other user (i.e., the invitee-user to whom the decomposed task is sent). For example, the restriction may expressly identify a user, a user's role, a user's function, a user's title, and the like, and then make the restriction to one or more portions (e.g., fields) of the application form. Although the previous example describes the restriction as a read-only restriction, other restrictions may be used as well including one or more of the following: hide a field, and a mask a field. For example, secretary 302 may want to hide information sensitive information regarding the person that is about to be hired to prevent an invitee from seeing that sensitive information.

At 246, the selected task (including any restrictions) may be provided to another user (e.g., a so-called invitee-user) on an ad hoc basis. For example, secretary 302 may decompose the task 312 into a subtask to obtain salary information and restrict the application form so that only that salary field can be modified. Next, secretary 302 may select another user (i.e., the invitee) to receive the selected decomposed task. For example, the salary subtask may be provided via email (either independently of the application form or as part of the application form) to another user, such as professor 304. In this example, the professor 304 may not know the salary and provide the decomposed task to an accountant 306. Professor 304 and accountant 306 would each have a corresponding user interface, such as user interface 105 coupled to server 160.

At 248, when a decomposed task is completed, the decomposed task is received at an inbox (e.g., at server 160), and an indication (e.g., an email or other like notification) is provided to the user, such as secretary 302 at user interface 105.

At 250, the workflow process may continue. For example, secretary 302 may complete using user interface 115 the form at 314, provide (e.g., via server 160) the completed application form for signature (or approval) to professor 304, and, once approved, professor 304 may send (e.g., by indicating approval at a user interface and selecting send) the application form to accountant 306 for final signature and filing (e.g., storage) of the application form. At 320, the workflow 300 is complete.

FIG. 1B depicts another implementation of system 100. Specifically, FIG. 1B depicts server 160 including a user management and security subsystem 164A for confirming the identity (e.g., with a login and password) of users, a task management subsystem 164B for managing (and/or controlling) the tasks of the work flow, and a user interface subsystem 164C for generating pages (e.g., hypertext markup language pages of for presentation at user interface 105 (e.g., pages including tasks, such as page 400). User management and security subsystem 164B may access information 164D regarding users of the system (e.g., a list of users and their rights). Task management subsystem 164B (which includes task decomposer 162 (labeled TD 162) may access information 164E defining the tasks of the workflow and the instances of those tasks in the workflow.

For example, when a task is decomposed, a request is sent from user interface 105 to task management subsystem 164B, where the task included in the request is decomposed by task decomposer 162. Next, the task decomposer 162 takes the request with the information about the invitees (to which the decomposed task will be sent) and, based on the information at user management & security subsystem 164A, confirms whether the secretary 302 has the appropriate rights to decompose the task and whether the invitees are authorized to provide the secretary with the missing information. If so, the task decomposer 162 decomposes the task into subtasks. Once the invitees open their work list at a user interface, they will find the new tasks assigned on to their name. Opening the task(s) will again result in a roundtrip to the server, which then in turn yields a response rendered by the user interface which essentially reflects the settings made by the secretary about which information is read-only, hidden, or modifiable by the invitee.

FIG. 4 depicts an example of a form presented at user interface 105 for decomposition to another user. The user, for example, secretary 302 may be presented at user interface 105 with form 400 and then decompose a task by, for example, selecting which portions of form 400 will be provided to another user (e.g., an invitee). For example, the user may select Adam as the invitee and decompose the task by providing only the position name and salary. In the example of FIG. 4, the restrictions are listed as visibility rights 418A, and the job description is read-only 418B (i.e., the invitee can only read the description of developer and cannot change it), while the salary information is modifiable 418C (i.e., the invitee can write to that field in the form). Once the secretary is ready to delegate the decomposed task, the secretary may select delegate 420 to provide (e.g., send) that task via server 160 to the invitee which in this example is the user Adam.

Form 400 also includes other features, such as a message field to allow embedded messages (e.g., a message stating “help me with this subtask,” “hello,” “urgent,” and so forth); a stay responsible for process field (e.g., the user that delegates the decomposed task maintains control and responsibility for the subtask within the overall workflow); a deadline field (e.g., to include a date for completion); and a set all rights field (e.g., to set all visibility rights 418A) to, for example, one of the listed restrictions (e.g., writable, read-only, and invisible).
